Confusion with the log

I've always wondered what "banana free" meant. I'm assuming lesbian sex but I'm not a lesbian and I don't know if I should pick it or not. The reason is because my bf sometimes rubs me and such like how I would masterbate (I don't), but I don't know what to call that. I'm not master bating because it's my bf doing it, since on the log it says "all me", but it's also not sex so I can't choose that. So what do I put down?
